Product Description for the ADAM Sub2100

ADAM Audio subwoofers are designed with one primary goal in mind: Achieving absolute accuracy and an authentic natural sound in the process of music reproduction. This means combining exceptional bass power with precision and clarity in every subwoofer. These elements are the perfect partners to complement the highly acclaimed clarity and transparency of ADAM monitors in the lower and lowest frequencies.

All subwoofers feature both balanced (XLR) and unbalanced (RCA) input/output connectors and comprehensive control options that allow for adapting to different room acoustics and requirements.

Panel / Controls

All subwoofers feature a level control (-60dB to +6dB), phase switch (180°) and a variable upper frequency control (50-150Hz). For the satellite outputs, an 85Hz high pass filter can be switched in to block frequencies below 85Hz so satellite speakers can meet the Dolby recommendations for theater sound and also to relieve the satellites from the lower frequencies. In addition, you can either switch on/off the subwoofer manually or use the option of automatically powering up the subwoofer whenever it receives a signal (‚signal-on/ continuous').


ADAM has developed the unique Sub2100 subwoofer for the special requirements of large control rooms and studios. The Sub2100 combines a huge 21.5"" woofer and an amplifier capable of 1000W continuous power housed in a bass reflex enclosure tuned for reproducing frequencies down to 18Hz. The sheer power and extremely high efficiency (99dB/ W/m) enable this system to produce linear SPL peaks of ≥128dB without any significant compression.

The world‘s largest voice coil

Essential to the volume of this woofer is the gigantic 6” voice coil, which is the largest worldwide. Equipped with this voice coil, the Sub2100 is capable of reaching the highest SPLs in the lowest frequencies that can be perceived by the human ear. On every level, the Sub2100 establishes a new benchmark in subwoofer technology.
